RNA Quality Control Using External Standard RNA

RNA Quality Control in Eukaryotes

Eukaryotic cells contain numerous RNA quality-control systems that are important for shaping the transcriptome of eukaryotic cells. These systems not only prevent accumulation of nonfunctional RNAs but also regulate normal mRNAs, repress viral and parasitic RNAs, and potentially contribute to the evolution of new RNAs and hence proteins. These quality-control circuits can be viewed as a series ...

RNA nanotechnology breakthrough for targeted release of RNA-based drugs using cell-based aptamers

Nucleic acids play different roles besides storing information and proteins coding. For example, single-stranded nucleic acids can fold into complicated structures with capability of molecular detection, catalyzing bioreactions and therapy. The development of RNA-based therapies has been rapidly progressed in the recent years. RNA aptamers are biomolecules with a size of 10 to 50 nm that can be...

RNA Integrity Number (RIN) – Standardization of RNA Quality Control Application

The assessment of RNA integrity is a critical first step in obtaining meaningful gene expression data. Using intact RNA is a key element for successful microarray or RT-PCR analyses. The Agilent 2100 bioanalyzer and RNA LabChip kits play an important role in assisting researchers in the determination of RNA quality. Profiles generated on the Agilent 2100 bioanalyzer yield information on concent...

Enhancement of RNA Interference Effect in P19 EC Cells by an RNA-dependent RNA Polymerase

Background: RNA interference (RNAi) is a phenomenon uses double-stranded RNA (dsRNA) to specifically inhibit gene expression. The non-specific silencing caused by interferon response to dsRNA in mammalian cells limits the potential of utilizing RNAi to study gene function. Duplexes of 21-nucleotide short interfering dsRNA (siRNA) inhibit gene expression by RNAi. In some organisms, siRNA can als...
